A&W Restaurants, Inc., is a chain of fast-food restaurants distinguished by its draft root beer and root beer floats. A&W was arguably the first successful food franchise company, starting franchises in California, in 1923. The company name was taken from the surname initials of partners Roy W. Allen and Frank Wright. The company became famous in the United States for its "frosty mugs," where the mug would be kept in the freezer prior to being filled with root beer and served to the customer.More from Wikipedia
